Hello there, well I recently had my Motive 4.56's () installed, still in the break in phase. But I did cruise for a few minutes at 2000rpms and my Delta 50 FM (dronemaster I now know it as) is bloody annoying now . . . miss the silence it produced at 1500-1750rpm (60-80mph) my 3.21 gears gave me LoL . . .

So in a nut shell I'm transitioning from DM to either a CB, AT3030, or Magnaflow . . . what I'm curious in are personal videos or knowledge of their mufflers at certain RPM ranges, preferably in the 2000-2200 highway cruise rpm range because that's probably where I'll be after the break in phase and I get the cruise the highway faster than 60-65. But with the 4.56's now I probably wont go above 65-70, due to higher seems to diminish mpg.

In advance, Thanks those who help me out in my decision .

 

My magna SI/SO catback exhaust does seem to have a bit of a drone right at 2000rpms. At 2200+rpm the truck seems to lose the drone but it is not entirely quiet. For my applications (young guy and few long highway trips) this system is sweet. Chances are if your older or really want something quiet the magnaflow setup will not be the best. The AT3030 XL has een getting good reviews for not having any drone.

 

Can't say I'm an old guy either, 20yo here. But that's a rather perfect match up to how the Delta 50 FM behaved during my highway drive I did. The rpms were roughly exactly at 2000:63-65mph. Guess I'll have to take another drive in a few hundred miles and take it up to 2100-2200 rpms and see if the drones still there, more than likely will be . . . and this is why I'm lookin at others interior noise ranges from CherryBombs, AT's, and Magnaflows

 

I've got a Cherry Bomb Extreme, and at highway cruising speed you know it's there. It doesn't drone, but it's still a Cherry Bomb. It's a great muffler, but not the one you want if you want a quite cruise.
